<div dir="ltr">Dear Kirk - <div><br></div><div>''<span style="font-family:Arial">Dieter has brought up the concept of retained heat cooking in an insulated container. Would anybody even need turn-down in a cook stove? Is retained heat cooking the better solution, or is it good to have both?'' </span></div><div><span style="font-family:Arial"><br></span></div><div><font face="Arial">I think it would very much depend on what is being cooked and in what type of kitchen setting. If this question of ambient air temperature has more than noticeable effects on the stove performance, then it is something I imagine a cook would approve or disapprove of and that can make or break a sale (or a 'user' using in the case of a free stove).</font></div><div><font face="Arial"><br></font></div><div><font face="Arial">Say you sell the same stove to be used in an igloo as for a maasai manyatta...would your customer notice any differences that would affect the quality of making dinner etc.? Retained heat works for some foods, but for staples like fufu, (sima or ugali) that need to be boiled, and then vigorously stirred and then simmered it gets tricky as does stir-frying.</font></div><div><font face="Arial"><br></font></div><div><font face="Arial">There is (a simmering?) demand in Kenya for simmering cookstoves in SME settings, the popular one right now is a smokey sawdust stove that is basically a metal cylinder with a door tube that you pack with saw dust around two glass bottles stacked like a rocket stove - you then remove the bottles and fill with firewood and light the bottom side. This lets the water boil on the firewood phase and then the slow burn of the saw dust keeps the water simmering. They are used by 1000's of small eatery joints around Kenya for keeping goats head soup warm and also keeping ugali (like polenta) warm wrapped in polythene plastic bags! </font></div><div><font face="Arial"><br></font></div><div><font face="Arial">I would like to know more about all these different tests Crispin mentions - how many cookstove tests are there in total? Between the VITA the ProBEC and the StarSOP, who uses which tests...do the various Govts. and Donors agree on one test for the most part? I do suppose though that given the phenomenal variations in global cooking and fuel type that an equally complex set of testing procedures would be needed. My only concern is how does the end user of the stove make use of this information in their day to day life? Do any of them provide for a simple energy star style of rating for ease of laymans understanding? What would the 'stars' be for, emissions, efficiency, durability, safety? </font></div><div><font face="Arial"><br></font></div><div><font face="Arial">Many thanks, <br><br></font></div><div><font face="Arial">Teddy </font></div><div><font face="Arial"><br></font></div><div><font face="Arial">On post note: </font></div><div><font face="Arial">In regards to cooking in igloos - Wiki says a <a href="https://en.wikipedia.org/wiki/Kudlik#/media/File:Qulliq_1999-04-01.jpg">Quilliq</a> is used to burn seal or whale fat...I wonder what tier these would fall under?

<p class="MsoNormal"><span style="FONT-FAMILY:'Calibri','sans-serif';COLOR:#1f497d;FONT-SIZE:11pt">You
may have been mistaken. I think what happened was that the ambient room
temperature changed the measurement you were attempting to make. At the
higher ambient temperature there was less rate of heat loss from the cooking
pot, so it took less fuel to keep it hot and the turndown ratio – as you
define it – changed. So the problem may lie with your definition of the
turndown ratio. I use the minimal sustainable firepower, determined from
the rate of fuel feed which just keeps the fire going, as my lower measure,
and the maximum firepower I can achieve without significant oxygen starvation
as the upper one, and have yet to see the sort of effect of ambient
temperature on the ratio of the upper to the lower that you report with your
definition of the ratio.<u></u><u></u></span></p>

represented in the VITA International Standard test, the result of several
well funded international conferences, obscure in 2003? Both the Indian and
Chinese governments developed tests of their own widening the scope of PHU
to include power, rate of evaporation, time. Visser (2003) published a
version of a water boiling test based on efficiency and appropriate power
for boiling and simmering. What motivated this parallel activity? Why isn’t
the VITA test in more general use?”<u></u><u></u></span></i></p>
<p class="MsoNormal"><span style="FONT-FAMILY:'Calibri','sans-serif';COLOR:#1f497d;FONT-SIZE:11pt" lang="EN-CA"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="FONT-FAMILY:'Calibri','sans-serif';COLOR:#1f497d;FONT-SIZE:11pt" lang="EN-CA">One reason the VITA test was not more popular was it had several
conceptual errors and a few really poor metrics that gave mis-directing
outputs. One is the efficiency of simmering, another is the concept of
specific fuel consumption for simmering. Another was the idea of an
‘average efficiency’ meaning an ‘average thermal efficiency’. I believe from
my research that the specific fuel consumption for simmering and the average
efficiency were both introduced by Baldwin in 1986 or so, before his book
came out. Neither are acceptable metrics.<u></u><u></u></span></p>

<p class="MsoNormal"><span style="FONT-FAMILY:'Calibri','sans-serif';COLOR:#1f497d;FONT-SIZE:11pt" lang="EN-CA">The document refers to the VITA test the ‘international standard’
which is not supported by the evidence. Three or four minor parties agreed
to it and it was never used by the major markets in India and China. Even
Eindhoven University didn’t use it and they were a party to drafting it.
India pretty much adopted the minority position taken by KK Prasad from
Eindhoven and built that into their 1991 test. The Chinese test from that
era was very similar. India, interestingly, produced a list of 28 standard
sizes of cooking pot which is a record, I believe!<u></u><u></u></span></p>

<p class="MsoNormal"><span style="FONT-FAMILY:'Calibri','sans-serif';COLOR:#1f497d;FONT-SIZE:11pt" lang="EN-CA">The long-forgotten organisation Bois de Feu had a clear
understanding of these issues and had a test method in 1982 that didn’t have
these problems. They treated the simmering phase very carefully (and
differently). Prasad (and Visser who was his student) developed multiple
test methods over the years. Piet Visser and I created one in Malawi in
about 2007 which later evolved into the ProBEC Test for heat transfer
efficiency which is now a SeTAR SOP, currently v1.05 (SeTAR is an
independently managed continuation of the 13 year long GIZ/ProBEC project).
It doesn’t really predict performance, it gives a real-time heat transfer
efficiency report under varying conditions. It is very easy to perform and
it supports pot-swapping, similar to the Indian
protocol.<u></u><u></u></span></p>
